7 Claims.

This invention relates to electric vibrators for massaging purposes and has for its object to provide a new and improved construction for such an apparatus.

Another object of this invention is to provide a novel form of casing for the vibrator.

A further object of this invention is to provide a novel mounting for the vibrator in the casing thereof.

These and other objects of this invention will become more readily apparent from the detailed description thereof whichfollows, reference being had to the accompanying drawings in which-- Figure 1 is a side elevation of the electric vibrator with portions of it broken away to illustrate the construction thereof.

Figure 2 is a vertical sectional view of the vibrator, the section being taken on the line 2-2 of Figure 1.

Fig. 3 is a side elevation with the casing and locking band shown in longitudinal diametral section;

Fig. 4 is a plan view of the casing, locking band, and supporting partition shown in section, taken perpendicular to the plane of Fig. 3;

Fig. 5 is a plan view of the locking band, with parts broken away and in section;

Fig. 6 is a transverse vertical sectional view of the locking band taken on the line 66 of Fig. 5; and

Fig. 7 is an end view of the supporting partition, showing the tongue structure to which the magnet is attached.

In the figures of the drawings like reference numerals indicate like parts.

The vibrator construction, including its casing and the mounting of its mechanism within the casing forming the subject matter of my present invention, eliminates all visible mounting and fastening means from the outside of the casing so that its appearance is not marred by the presence of screw heads or other fastening means on the outside of the casing.

This has been accomplished by the novel form of casing for the vibrator which comprises a pair hollow shells l and 2 and the supporting partition 3, all of which are locked and fastened together by means of the locking band 4. For this purpose the open ends of the shells I and 2 are ex panded to provide an annular shoulder 5 suitably spaced from the open ends of each of the shells. In addition an outwardly flaring flange 6 is provided on each of the shells so as to surround the 55 open ends thereof and engage and hold between them the flange 1 which encircles the supporting partition 3 and forms a part thereof.

The locking band 4 is concaved and on each side is provided an inwardly projecting flange 8 which engages behind the annular shoulders 5, 5 of the shells of the casing so as to hold the shells together and hold the supporting partition rigidly clamped in place between them. The free ends of the locking band i are bent out and shaped into substantially semicircular channel members or sleeve portions 9 and H] which are adapted to tightly flt around and embrace the mounting tube II and with this tube telescope into the hollow end of the handle 12 to be held together thereby with the casing supported thereon. Mounting tube I! is carried by partition 3 and passes through an aperture in the casing. To hold the ends of the locking band in place in the handle after they have been inserted therein, suitable barbs l3 are struck up on the outside of the channel shaped ends which engage and dig into the inside of the handle and keep the ends of the locking band from sliding back out of the handle.

The supporting partition 3 is concaved in such a manner that by clamping the flange 1 thereof between the shells, as above described, it automatically holds the partition centered in the shells and divides the inside of the casing into a front and back air chamber. a

The operating mechanism of the vibrator is mounted in the concaved side of the supporting partition 3 and comprises an electromagnet having a central core l4 surrounded by the magnet winding Ill. The electromagnet is centrally mounted in the substantially U-shaped magnet l6 and the core I4 is fastened thereto so as to have the parallel sides of this U-shaped magnet located and equally spaced from the outside of the magnet winding parallel to the core I4.

An armature I! is suitably held spaced from the core l4 and the ends of the U-shaped magnet I6 and is held suspended in front of the electromagnet to be vibrated thereby. For this purpose a bracket I8 is formed as part of the armature and extends to one side and rearwardly to the back of the electromagnet where it is held clamped to the supporting partition 3 in conjunction with the electromagnet.

At the front of the armature is provided the extension rod l9 which projects thru the end of the casing 2 and has the massaging member 20 attached thereto to cause this member to vibrate when the electromagnet is rapidly energized and deenergized by an alternating current which attracts and repulses the armature l'l according to the frequency of the alternating current. The wire which connects to the electromagnet to furnish the electric power for the operation of it passes thru the hollow handle and the mounting tube II. This tube is welded or otherwise fastened to the supporting partition 3 so that this tube and the ends of the locking band jointly support the casing on the handle.

I claim:
